Abstract

Stock assessment studies of Sardinella Lemuru Bali strait indicate overfishing. The growth of fishing vessel numbers result on fish biomass stock reduction. Sustainable fishery management in overfishing area can be done by limiting number of fishing effort. There are three kinds of methods approach on determine number of fishing effort and total allowed catch (1) Maximum Sustainable Yield (MSY), (2) Maximum Economic Yield (MEY) and (3)Maximum Social Yield (MScY). Sustainable fishery has three main aspect as its indicators; ecology, economic and social. This research attempts to simulate three kinds of methods to the indicators of sustainable fishery (1) biomass fish stock as ecological aspect, (2) profit of purse seine fishing vessel as economical aspect and (3) numbers of fishers involved in the business of marine capture fishery represents social aspect. System dynamic method and powersim software are used in simulation model. Simulation output shows that fish biomass stock can be maintain in sustainable level by applied fishery policy. Limiting number of fishing effort create balancing between fish stock natural growth and fish harvest. This policy starts to apply on year 2010 in simulation model and run until 2030 to forecast future condition of fish biomass stock.

Abstract

The multi-depot vehicle routing problem (MDVRP) is addressed using an adaptation of the variable neighborhood search (VNS). The proposed VNS algorithm besides using several neighborhoods and a number of local searches has a number of additional features. These include a scheme for identifying borderline customers, a diversivication procedure and a mechanism that aggregates and disaggregates routes between depots. The proposed algorithm is tested on the data instances from the literature and produces competitive results.

Abstract

Stock control is the most important aspect in an inventory system. It determines the safety stock in order to ensure that products are readily available when the customers require them. The decision makers in organizations tend to rely on software solution in obtaining stock control solutions since they have to manage a massive number of Stock Keeping Units (SKUs). However, managers intervene in the system and use their judgement to adjust or decide on various quantitative elements. This research discusses the effects of combination of stock control methods. An extended database of approximately 1,800 SKUs from an electronics company is analyzed. Then, a simulation experiment is performed in order to evaluate in a dynamic fashion what are the effects of applying combined stock control methods. The findings indicate that the combined method of stock control seems to improve the performance of the inventory system, especially in reducing inventory investment.

Abstract

Gold is one of the most enticing commodities and a very popular way of investing. Gold’s price is allegedly influenced by another factors such as US Dollar, oil’s price, inflation rate, and stock exchange so that its model is not only affected by its value. The aim of this research is to determine the best forecasting model and influencing factors to gold’s price. This research is modeling gold using multivariate analysis and reviews the univariate modeling as a benchmark and comparison to the multivariate one. Univariate time series is modeled using the ARIMA model which indicates that the fluctuation of the gold prices are following the white noise. Gold’s multivariate modeling is built using the Vector Error Correction Model with oil’s price, US Dollar and Dow Jones indices, and inflation rate as its predictors. Research’s result shows that the VECM model has been able to model the gold’s price well and all factors investigated are influencing gold’s price. US Dollar and oil’s price are negatively correlated with gold’s price as the inflation rate is positively correlated. Dow Jones Index is positively correlated with gold’s price only at its first two periods.

Abstract

This paper presents a case study in selecting the best location for a Floating Storage and Regasification Unit (FSRU) in Bali. FSRU is an alternative to replace a conventional shore LNG terminal. The selection involves several criteria/attributes that can be grouped into two general criteria, namely qualitative and quantitative criteria. Multiple Criteria Decision Making (MCDM) approach is utilized to solve the selection problem, considering the capability of this method in solving multi-criteria problem with mutual conflict. Qualitative criteria are evaluated using AHP method to calculate weight of each criterion. Moreover, decision matrix algorithm is then utilized to convert preference of stakeholders into, consecutively, probability assignment, total probability assignment and preference degree eventually. Quantitative criteria are also converted into preference degree and entropy method is used to rank the alternatives. Selected location would be the alternative having the highest entropy. Four alternatives are under consideration. Those alternatives are Benoa, Celukan Bawang, Pemaron and Gilimanuk. This research found that Celukan Bawang is the best location for the FSRU. Abstract in Bahasa Indonesia: Paper ini menyajikan pemilihan lokasi Floating Storage and Regasification Unit (FSRU) untuk proses distribusi LNG dari Ladang Tangguh ke Bali. FSRU merupakan alternatif pengganti LNG receiving terminal di darat. Pemilihan lokasi ini melibatkan kriteria kualitatif dan kuantitatif dan metode Multiple Criteria Decision Making (MCDM) digunakan untuk melakukan pemilihan mengingat metode ini dapat memberi solusi tepat saat mutual conflict terjadi pada beberapa kriteria pemilihan. Penilaian terhadap beberapa alternatif didasarkan atas nilai masing-masing kriteria yang diperoleh dari kuisioner terhadap beberapa stakeholders. Untuk kriteria kualitatif dicari relative weight dengan menggunakan metode Analitik Hierarki Proses (AHP). Nilai relative weight ini kemudian konversi menjadi normalize relative weight, basic probability assigment dan total probability assigment hingga kemudian diperoleh nilai preference degree dari kriteria kualitatif. Selanjutnya nilai prefrence degree kriteria kualitatif ini digabungkan dengan nilai preference degree dari kriteria kuantitatif dan merankingnya dengan metode entropy. Alternatif lokasi yang terpilih adalah alternatif dengan nilai entropy tertinggi. Melalui proses seleksi awal, empat alternatif menjadi kandidat lokasi. Alternatif tersebut adalah Benoa, Celukan Bawang, Pemaron dan Gilimanuk. Hasil dari penelitian ini menunjukkan bahwa alernatif lokasi yang paling sesuai untuk lokasi penambatan FSRU adalah Celukan Bawang. Kata kunci: MCDM, AHP, kriteria kualitatif, kriteria kuantitatif.

Abstract

Literature on packing problems in general is extensive and too broad to be covered here. One of the packing problems is packing for cylindrical material, that is packing for pipe. To pack the pipes, a mathematical model non linier mixed integer programming will be applied to explain packing problem mathematically. A combined genetic algorithm and tabu list is suggested to solve the mathematical problem to obtain satisfactory solution in terms of packing configuration and computational time. The algorithm gives a good result in terms of space utilization and computational time. Abstract in Bahasa Indonesia : Literatur mengenai permasalahan pengepakan (packing problem) secara umum telah dipelajari secara intensif dan sangat luas pengembangannya. Salah satu masalah pengepakan yang ada adalah masalah pengepakan silinder. Pada tulisan ini diteliti mengenai masalah yang merupakan bagian dari pengepakan silinder yaitu pengepakan pipa. Dalam pengepakan pipa digunakan model matematis non linier mixed integer programming untuk menerangkan permasalahan pengepakan secara matematis dan menyarankan menggunakan metode heuristik algoritma genetika (genetic algorithm) dipadukan dengan penggunaan daftar iterasi tabu untuk menyelesaikan model matematis yang dihadapi sehingga solusi yang dihasilkan dapat memuaskan ditinjau dari sisi konfigurasi pengepakan dan juga efisien ditinjau dari waktu komputasi. Algoritma yang diusulkan pada tulisan ini mampu memberikan konfigurasi pengepakan pipa yang memuaskan bila ditinjau dari pemanfaatan ruangan dan waktu komputasi yang cepat. Kata kunci: pengepakan pipa, model matematis, Algotirma Genetika.

Abstract

This paper discusses a variant of the basic vehicle routing problem (VRP) by including the following characteristics: fleet size and mix, multiple trips, split delivery, and multiple compartments. One of real cases of this problem is related to determining tanker’s routes in delivering fuel products from a supply port to a number of destination ports. Each tanker has several compartments where each compartment is dedicated to a certain fuel product. In this paper, a solution approach based on genetic algorithm (GA) is proposed and tested using nine hypothetical instances. Experiment results show that the proposed GA gives consistent results measured by coefficient variations
